David - first off, want to thank you for this awesome series of articles on Server Overview. I built an Overview package and its been running for about 3 months. Its been fantastic and it's made the DB team look good on several occasions already by being proactive instead of reactive about server and db issues. We love it!

My question is, do you know if there is a way to add a check for seeing when a cluster has a failover? Perhaps a ServerProperty or some way to query a Last Failover Date or something like that? Any thoughts would be helpful....thanks!
